Abstract The main goal of this work is to show the new approach to determining safety technological levels (SLs) in terms of water quality and its chemical stability, as well as issues of water corrosion properties in water distribution systems (WDSs), due to the fact that water supply pipes are prone to corrosion. In the paper the methodology of determining the risk associated with threat to technical infrastructure was considered. The concept was studied on the basis of real operational data from the water treatment plant. The probability of exceeding the individual parameters for WTPI is slightly larger than for WTPII, which means that this water treatment process may cause lack of chemical stability in the water supply network. Operators should anticipate in the process of designing water distribution system, using proper materials, as to ensure an adequate level of safety from the water source to the water recipient. It should be noted that it is necessary to adjust the material of internal installation of water supply networks to the parameters of the water. At present, there are no correlations between the designing step and water parameters. It was concluded that to protect the water supply infrastructure, which belongs to critical infrastructure, water company should put more emphasis on distribution of stable water that has not potentially corrosion properties. Some suggestions were made for the protection of WDS and to ensure safety of system functioning and long-term usability of water pipes.

根据所需的技术安全水平分析自来水的化学稳定性

摘要 这项工作的主要目标是展示在水质及其化学稳定性以及配水系统 (WDS) 中的水腐蚀特性问题方面确定安全技术水平 (SL) 的新方法，由于事实上，供水管道容易腐蚀。本文考虑了确定与技术基础设施威胁相关的风险的方法。该概念是在水处理厂的实际运行数据的基础上进行研究的。WTPI 超出个别参数的概率略大于 WTPII，这意味着该水处理过程可能会导致供水网络缺乏化学稳定性。操作人员在设计配水系统的过程中应该预见到，使用合适的材料，以确保从水源到水接收者的足够安全水平。需要注意的是，给水管网内部安装的材料需要根据水的参数进行调整。目前，设计步骤与水参数之间没有相关性。得出的结论是，为了保护属于关键基础设施的供水基础设施，自来水公司应更加重视分配没有潜在腐蚀特性的稳定水。提出了一些建议，以保护WDS，确保系统运行的安全和水管的长期使用。需要注意的是，给水管网内部安装的材料需要根据水的参数进行调整。目前，设计步骤与水参数之间没有相关性。得出的结论是，为了保护属于关键基础设施的供水基础设施，自来水公司应更加重视分配没有潜在腐蚀特性的稳定水。提出了一些建议，以保护WDS，确保系统运行的安全和水管的长期使用。需要注意的是，给水管网内部安装的材料需要根据水的参数进行调整。目前，设计步骤与水参数之间没有相关性。得出的结论是，为了保护属于关键基础设施的供水基础设施，自来水公司应更加重视分配没有潜在腐蚀特性的稳定水。提出了一些建议，以保护WDS，确保系统运行的安全和水管的长期使用。自来水公司应更加重视分配没有潜在腐蚀特性的稳定水。提出了一些建议，以保护WDS，确保系统运行的安全和水管的长期使用。自来水公司应更加重视分配没有潜在腐蚀特性的稳定水。提出了一些建议，以保护WDS，确保系统运行的安全和水管的长期使用。
